Yarra:
There are two versions - the CLIENT is the one you want IF you are trying to talk with the forum members. Make sure you have that part correct. The Server is for IF you wish to host your own and have other people use it as their chatroom. Let us know which you are using

Good luck.
PS... you said windows in your post, so compatability should not be an issue.
remember my IP address is 68.39.144.212 - server name is beemasterforums (you don't need the password) again, good luck. Come around in the evenings EST and you'll find the most people on to help setup the final voice settings if you need help. The whole thing should take only a minute or two.
